Why Southeast Seattle?

Question How does transit connectivity, that is the linkage between residential areas and points of interests (land use parcels of services and amenities) as provided by bus routes, vary in Southeast Seattle?

Findings & Analysis

● I-90 Junction ● Rainier Beach area ● Martin Luther King Jr. Way S. corridor Diversity Index Number of Accessible POIs

Findings & Analysis Number of Accessible POIs Downtown U District I-5 Corridor North of Canal

Limitations Frequency of service Transfer POIs within block groups are also included POI data mainly for Seattle Euclidian vs. Network Distance Other modes of transit excluded (Light Rail, Sound Transit buses)

Implications & Next Steps Diversity index of census block groups reveals connectivity to services and amenities King County Metro can use the diversity index to improve services Apply similar methods to entire city
